PATENT OFFICE `NATl'rIl-klil' GOLDBRG, WILLIAM GOLDBERG, AND JACOB M.GOLDBERG, 0F -DENVEIL .COLORADO A 1 FoLnIive .AwNiNGfARM ThisQinventionrelates to improvements in folding awning arms of the type described andclaimed in U. S. PatentNo. 1,742,234, .i granted January 7 1930,'. to F.:R1-Clifton. lIt is the object of thisoinvention to produce an improvedbracket or supporting meansfor arms of this type that shallbe soconstructed that the inclination of the arm with respect to thesupporting surface can be readily adjustedl and held in yadjustedposition. A

Another object of this invention is to produce an improved constructionof the s... extensible arm sections so as to increase the strength Landrigidity of the arm without materially increasing-its weight. The aboveand otherobjects that may become apparent as this description proceedsareattained by meansof a construction and anarrangement of parts thatwill now be described in detail, and for this purpose reference will behad to the accompanying drawings in which the preferred embodiment ofthe invention has been illustrated, and in which: l' s Fig. 1 is a sideelevation ofan awning supporting arm fr showing the same .in extendedposition `and secured to a 'vertical s supporting surface; Fig. 2 is asection taken on line Fig. l;

Fig. 3 is a section taken online 3%3, Fig. 2;V

Fig. 4 is aside elevation ofthe supporting bracket and associated partswith the arm removed; l

Fig. 5 is a section taken on line 5,-5', Figli? o o. Fig. 6 is a sectionVtakenon line 6--6, Fig. 4;and A i Fig. 7 is a section taken on line7-7, Fig. 4. l

In the drawings reference numeral -1 indicates a vertical supportingsurface as, for example, the outside of a building. Secured to thesupporting surface is abracket comprising a base 2 that is perforatedforthe reception of securing bolts Extending outwardly from the base isa wall orweb 4 whose outer edge is provided with aange Application `ineareinar# 27, 1931- serial no. 511,534.

5. The flange has been shown asextending to both sides of the wall' asindicated in Fig. 6, but may be located entirely onone side 1fk desired.The flange extends entirely around the wall 4 and has its'ends inthebase 2. Thearrangement of Wall 4' and flange 5 gives to this part themaximum strength for the amount of material elnployed. 'The wall' 4`isprovided with an opening 6 for the reception of a`bolt`7 that serves asa pivot for the `U-shaped supporting bracket 8. This bracket Visprovided withtwo outwardly extending lugs or ears 9 and 10, that areperforated as indicated by reference numeral 11. 4 The wall 4 isprovided With an `arcuatejslot 12 that is concentric with the. opening'6 and the support 8 khas a projection 13` that' extends'over thearcuate slot and is perforated for the reception of a-clamping bolt 1,4.An adjusting device comprising a bolt 15 is associated with the bracketand the support and the bolt passes through an opening in flange 5 inthe manner shown in Fig. 7. Y The inner end of the bolt is provided witha nut 16 that has an outwardly extending projection 17` that engagestheU-shaped support to the rear of the lower-'end thereof. Secured tothe `U-shaped support is ahinge member 18 that is provided withtwospaced arms that are located between the arms 9 and 10` and whicharep'erforated for the reception of the bolt 19. A tubular member 20 issecured to the hinge member 18 by means of rivets 21 and telescopically`connected with member 2O is another tubular'member. 22. Member 20'isprovidedv with two longitudinal lslots 23 and 24, andmember 22 isprovided with corresponding slots 25 'or it may be provided with "iroo - 6? porting. bracket is rotated about-its pivot to bolt 32 that canbe adjusted and held inadjustment by means of a locking nut 33.

cured to the hinge member 28 by the pivotv pin 30 is another hingemember 34 to which the tubular member 3-5` is secured by means of rivets36. Another tubular member 37 is telescopically connected with member 35and these two members are held in Vadjusted position by means of bolts26 in the Amanner described in connectionl with members 2'0 and 22.VSecured to the outer. end of member 37 is aV Z-shaped bracket 38 to theupper and outer end of which is secured asupporting' memberV 39 to whicha wooden bar 40 is' fastened.

Since the type of awning and awning support to which this inventionrelates is old and lwell known no attempt will be made herein todescribe the actual 'operation of folding' these supporting arms nor toshow the manner in which the canvas is secured in place. The inventionrelates more partic'ularly to the manner of supporting the two-part yarmso that the inclination of the arm with respectto the supporting surfacecan be readily adjusted to suit the particular conditions prevailing atthe point where the installation is made.

In the operation of installing and adjusting awning arms of this type,care must be taken to adjust the several arms to the Same inclination inorder to obtain satisfactory operation of the awning during the foldingand unfolding thereof. For the purpose of adjusting the inclination,vthe arms are supported from a U-shaped support 8 that in turn ispivotally attached to the wall 4 of the bracket by wmeans of a pivot 7.The wall 4 is provideduwith an j arcuate slot 12 for the reception of avclamping bolt 14 that extends through this slot and through a part-ofthe U-shaped support. When bolts' 7 and 14 are tightened, .the U- shapedsupport will be held `against rotation. In order toV facilitate ktheadjustment a bolt 15 has been provided. This bolt extends through anopening in flange 5. This bolt is provided with a nut 16 that has a lug17 that engages the rear surface ofthe supporting member 8 in the mannershown in thev drawings. When bolts 14 and 7 are loosened, the torqueexerted by the arm will be resisted by bolt 15 aiidfwhen this bolt isturned in either direction the U-shaped supthe extent required, and inthis way the inclination of the arm can be adjusted to the exactposition desired without making it necessary to have some one holdingthe arm as must be done if the supporting device is not provided withsomeV screw adjustment of this type. Attention is also called to thefact Ithat bolt 15 is undertension which greatly simpliies theconstruction. After thearm has been adjusted. to theV 'desiredinclination, bolts 14 and 7 are tightened so as to lhold the parts inadjusted position. The Atubular members can be made in any suitablemanner but in the embodiment illustrate'd, the tubular members are eachformed. from two similar sections, each provided withfflanges 41 thatare welded-'together and the inner tubular members have the weldedlportionsV pressed inwardlyin the manner shown in Fig. 3.

In order to assist in extending the arms after they have been folded andwhen the canvas is unrolled, a spring42 is provided and this spring iscoiled Vabout the pivot pin 30 and has its ends resting on the adjacentarm sections.
